A platform based shipping container with folding endwalls which enable the empty container to be stacked up with a pile of similar folded containers for economical transport. There is a twistlock at each corner to interlock folded containers together and a top lift aperture at each corner to enable the pile to be lifted from above. At least one endwall can also fold outwardly away from the base to provide a ramp for the loading of vehicles. The endwalls are resiliently biased to provide for folding in either direction.
